Introduction In this lab, we write a program that synthesizes 3 different types of waves at 3 different amplitudes and frequencies. To do this, we use a DAC0800 digital-to-analog converter attached to Port A on the Dragon12 EVB. We then view the output of the DAC on an oscilloscope. Equipment • 68HC12 evaluation board • MiniIDE and its respective requirements • DAC0800 digital-to-analog converter • ±18V power source • 10V power source • Oscilloscope Procedure 1. Create source data for the 3 different wave types using the equations given in the lab and store them in memory. The most negative voltage = 0, zero volts = 128, and the most positive voltage = 255. 2. Create a welcome message in memory. 3. Create a delay subroutine. 4. Create a subroutine that gets the keys the user types into the terminal and stores appropriate values into the WaveType, Frequency, Amplitude, and Duration memory locations. This subroutine returns to the main program when complete. 5.
